Defining Health Profession Regulators' Roles in the Canadian Healthcare System.

Health professions regulation today faces a myriad of challenges, due to both the perceived performance of regulatory colleges, how health systems have evolved, and even larger political and economic shifts such as the renegotiation of NAFTA. In this issue of Healthcare Papers, Wilkie and Tzountzouris (2017) describe the work of the College of Medical Laboratory Technologists of Ontario (CMLTO) to redefine professionalism in the context of these challenges. Their paper, and the comments of the responding authors in this issue highlight that there, is an overarching perception that health regulatory structures - across a range of professions - are not working as effectively as they should. Across this issue of Healthcare Papers, attention is drawn to the fact that more can be done to improve both the function and perception of professional regulatory bodies. However, each paper presents a different approach to how improvements in function and perception are possible.
